Install in reverse order of removal and note the following:

-- When reusing the ball joint, clean any remaining locking compound residue off the pin threads.

-- Bring the control arm with the ball joint into the installation position.

CAUTION:

There is a risk of damage occurring in the threaded connection area on the wheel bearing housing if handled incorrectly.

- Pay attention to the installation position.

Insert the ball joint -1- into the wheel bearing housing -2- up to the contact surface -arrows-.

-- Install the threaded connections for the components with bonded rubber bushings only until the stop, but do not tighten yet.

Bonded rubber bushings have a limited range of rotation. Only tighten the threaded connections for the suspension when the vehicle is at standard vehicle height.

-- Raise the wheel bearing to the standard vehicle height. Refer to WHEEL BEARING AT STANDARD VEHICLE HEIGHT, LIFTING VEHICLES WITH AIR SUSPENSION .

-- When tightening the threaded connection -1-, the control arm must be pressed toward the inside of the vehicle.
